MIXING NOZZLE.

Application led March 7,1927. Serial No. 173,309.

The invention relates to mixing nozzles, and particularly to nozzles for use inmixing oil with acid, although the nozzle is useful in other relations, wherein it is desirable to secure the intimatemixture of two or more liquids as they pass through a conduit. In the treatment of oils with acid, allalies, or other chemicals to remove sludge and impurities, it is necessary to secure a very intimate mixture of the oil and acid before they receive their alkaline treatment to neutralize the acid, and the present inven tion has for its primary objects theprovision of a simple nozzle construction which will give a very thorough mixing of the oil and acid. One embodiment of the invention is illustrated in the accompanying drawing, wherein Figure 1 is a vertical section through a pipe with two of the mixing nozzles mounted therein. Figs. 2' and 3 are sections von the lines II-II and III-III of Fig. 1. .And Fig. l is a section through a modified construction.

Referring to the drawing, 1, 2 and 3 are pipe sections provided with opposing pairs of flanges Ll, lsecured by the bolts 5. Two of the mixing nozzles are shown, but it will be understood that any number maybe used in series, or that-'a single one may be used, depending upon requirements.

The nozzles are cast of any suitable material, preferably of high corrosion resisting composition, such as high silicon ir0n,or a copper, aluminum, iron alloy, such as that known under the trade name of Alcumite. The casting comprises what may be termed an inlet portion A and a mixing portion B with a flange 6 clamped between the pair of opposing pipe ends. 1

rlhe inlet portion A fits easily in the pipe at 7, and rearward therefrom tapers to the left,` as shown, with the inclined inlet passages 8, 8 and a. central passage 9. Interiorly the inlet passage tapers to the right, leading at it-s reduced forward end into the mixing portion B. A pair of partitions 10 divide the main inlet passage into four parts, as indicated in Fig. 3.

The mixing portion B consists of a cavity 11 having its front wall provided with the four openings 12, 12, 12, 12 (Fig. 2), the central portion of such wall being provided with the cone 13.

Iihe liuidsto be mixed, vflowing to the right through the pip-es 1, 2 and 3, enter the openings 8 and 9, and are vbroken into a.

plurality of streams by the partitions 10, 10 (Fig. 3)', rwhichr are brought together in the tapering forward end of the inlet passage, andY discharged into the cavity 11 at an increased velocity. Four streams are. formed at this po1nt,.due to the partitions'- nozzle 16 on a line corresponding in locaf tion to the line II`II of Fig. 1. This nozzle is like that of Figsgl to 3, except that the front wall of the mixing chamber is provided with only two openings 14, 14

instead of the four openings 12, 12, 12, 12` 'H of the Fig-. 1 construction, and except that the wedge 15 is substituted for the con-e123vk of Fig. 1. In the longitudinal section, this nozzle is substantially the same as that shown in Fig. 1. The nozzle is capable of other modifications without departing from the broad invention involved.

lVhat I claimis:
